Background and History

In 1976 The United States Mint began to consider abolishing the current large size dollar coinage or making a new coin that was smaller and lighter in weight. Although Eisenhower dollars never widely circulated, the U.S. Mint and The Department of the Treasury was intent on keeping the one dollar coin. Keeping with the times, it was decided to portray a woman on the new smaller coin. It was decided that Susan B. Anthony, a pioneer of women's rights, would be portrayed on the new coin. Research indicated that the coin could easily be confused with a quarter, so an eleven sided rim was included in the design and a marketing campaign was mounted to educate the public. All of this was to no avail. The public still confused the new coin with a quarter and it never circulated widely. The reverse used the same design that was used on the previous one dollar coin, the Eisenhower dollar. No coins were made from 1981 through 1998. However, in 1999 an additional run was made to meet the demands of the vending machine industry. The next year the Sacajawea dollar was introduced. Prices for Susan B. Anthony dollars are affordable for all type of collectors.
